2. a) The sum of the interior of a triangle must add up to 180, however, 2 angles that form a line must also be 180 degrees. Therefore, angle 4 has to be equal to the nonadjacent interior angles since it must also add up to 180 with angle 3.

    b) 52 + 25 = 77
it would be a because the sum of the inside of a triangle must add up to one hundred eighty, also, 2 angles that make a line must also be 180 degrees. so after all that, angle 4 has to be equal to the interior angles since it must also add up to 180 with angle 3.  I HOPE THIS HELPS! :D
